Abstract
A method, a system, and a connectivity service network (CSN) for realizing a location service are provided. When a user terminal roams to the visited domain network from the home domain network, the H-CSN interacts with the V-CSN after receiving the location request, and obtains the location result through location control exercised by the V-CSN over the V-ASN, which realizes the location of the user terminal from the home domain network, and expands the application of the location service in the home domain network.
Claims13
A method for realizing a location service, comprising:
- receiving, by a home domain connectivity service network (H-CSN), a location request sent by a client;
- sending the location request to a visited domain CSN (V-CSN) after the location request is successfully authenticated;
- receiving a location result returned by the V-CSN, wherein the location result is information obtained from location measurement by triggering a visited domain access service network (V-ASN) after the V-CSN sends the location request to the V-ASN;
- and
- sending the location result to the client.
A system for realizing a location service, comprising a home domain connectivity service network (H-CSN), a visited domain CSN (V-CSN), and a visited domain access service network (V-ASN), wherein
- the H-CSN is configured to receive a location request sent by a client, send the location request to the V-CSN after the location request is successfully authenticated, receive a location result returned by the V-CSN, and send the location result to the client;
- the V-CSN is configured to send the location request to the V-ASN and receive the location result returned by the V-ASN;
- and
- the V-ASN is configured to obtain a location result after triggering location measurement according to the location request sent by the V-CSN, and send the location result to the V-CSN.
A connectivity service network (CSN), being a home domain CSN (H-CSN) that a user terminal belongs to, the CSN comprising:
- a first receiving unit, configured to receive a location request sent by a client;
- an authenticating unit, configured to authenticate the location request;
- a first sending unit, configured to send the location request to a visited domain CSN (V-CSN) after the authentication succeeds;
- a second receiving unit, configured to receive a location result returned by the V-CSN, wherein the location result is information obtained from location measurement by triggering a visited domain access service network (V-ASN) after the V-CSN sends the location request to the V-ASN;
- and
- a second sending unit, configured to send the location result to the client.
